Program to explain multiple catches.
In this program many catches are executed in a single try block. In Eve catch block throw occurs. Control selects the matching catch block . That matched catch block is executed. Then the control goes to the successive catch block to check it's matching.

Processes
A process is nothing but the execution period of a program. Or instance of a computer program. It contains the program code. There are certain processes depending on the level of execution by the operating system. New,ready,run,wait,terminate. New means the process is being created, Ready means that task or process is waiting to be allotted to any processor, Run means instructions are being executed Wait means that process is waiting for some other event to occur Terminate means the program or process execution has finished. There thread is a part of the process. Where the process has long time for termination and also execution . Depending on the operating system a process can be made up of multiple threads of execution where the instructions are executed concurrently.
Concepts of object oriented programming
This explains you the concepts of object oriented programming language. There are 7 concepts. 1. Objects 2. Classes 3. Data abstraction & Encapsulation 4. Inheritance 5. Polymorphism 6. Dynamic Binding 7.message passing. Here you know about the objects which are basic runtime entities. Class is a collection of objects. Data abstraction is nothing but revealing the essential features without telling about the background details. Inheritance is about the aquiring the properties of a parent class. Polymorphism itself tells that many forms of behavior. Dynamic Binding is the linkage of procedure call to the main code to be executed. Message passing explains how the communication takes place . These are the main concepts of object oriented programming language through c++ .
Internal commands and external commands of DOS
For example date,time,version,volume are the internal commands

Program to explain 1-D array implementing new and delete operator.
Here we are introducing two special operators in 1-dimensional array. They are new and delete. Here new is used to allocate space for an object. Delete is used for freeing the space which was previously allocated by new operator.
Handheld systems
This handheld operating system is nothing but what we use Android mobiles, Microsoft mobiles. The portables devices which we use in our hands and are carryable are called handheld operating systems. But these are not as fast as computer system . Here in this operating systems we use low processors compared to the computer systems. Here in this Android for example we use 128GB internal storage but where as in computer we get 1TB of internal storage. These are not as powerful as computer systems. Examples of handheld operating systems are PDA : personal digital assistants , tablet PC's , palm&pocket -Pcs ,cellular telephones,portable media plays,etc. Hand held systems are used all over the world , it's usage is high but not effective as computer . For ex: PDA is about 5inches in height and 3inches in width and also less than one-half pound. They have small memory because of their size. They sometimes hang like computer systems.
